Lab Safety – Biology 111 Lab 6 – Osmosis and Diffusion Goggles and closed-toed shoes are required! Gloves need to be worn. Do not open the demonstration petri dishes containing potassium permanganate. Potassium permanganate is an oxidizing agent. It increases the flammability of materials with which it comes in contact. Your TA will dispose of the potassium permanganate plates in the appropriately labeled waste container on the side counter. Do not open the antibiotic plates on demonstration. Dispose of Lugol’s solution in the base waste container on the side counter. Keep waste containers closed when not disposing of waste, and do not fill past indicated line on containers. Inform your TA of any full waste containers. Do not eat or drink in lab. Follow general safety precautions and use common sense in addition to these guidelines. Ask your TA if there is doubt about any procedure.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
